Process for the preparation of zinc dithiocarbamates
Zinc dithiocarbamates are obtained in especially readily filterable form and high purity when zinc salts are first added, in aqueous solution, to the secondary amines underlying the zinc carbamates, so that a zinc salt complex of the amines is formed, and carbon disulfide and then sodium hydroxide s...

| Zusammenfassung: | Zinc dithiocarbamates are obtained in especially readily filterable form and high purity when zinc salts are first added, in aqueous solution, to the secondary amines underlying the zinc carbamates, so that a zinc salt complex of the amines is formed, and carbon disulfide and then sodium hydroxide solution are then introduced, with stirring, into the aqueous suspension so obtained, the temperatures being maintained in the range from room temperature to the boiling temperature of carbon disulfide until the reaction has completely finished. |
